(on Android, 4 times out of 5 i accuse it of being x86 vs arm, and 4<br>
times out of 5 it's actually 32-bit vs 64-bit :-) )<br>

yeah, i was assuming you wouldn't know either --- i was hoping Eric<br>
would point us in the right direction again :-) (i did at least manage<br>
to follow his directions to get the full log without it being<br>
bizarrely restricted to a tiny scrolling area on my huge screen!)<br>
